ELECTRICALLY-OPERATED ORGAN-VALVE CONTROL.

Application filed March 27, 1928.

This invention relates to operating means for organs, and hasspecial reference to a magnetic control for admitting wind from the chest of an organ to the pipes, either directly, or indirectly by electropneumatic means.

One important object of the invention is to provide an improved magnetic control wherein the armature lever will be so constructed that the arms will be unequal, the arm which is moved toward the magnet by the magnetic force being longer than the arm which carries the valve, thereby making possible the use of a comparatively small magnet.

A second important object of the invention is to provide an improved construction of magnet, armature lever and hanged or support for the armature lever for the magnet the hanger also providing a valve seat for the valve combined in one unit.

A third important object of the invention is to so arrange the parts as to eliminate all springs, the longer arm of the armature lever acting as a counter-balance.

\Vith the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a section through a portion of a wind chest and showin the lower part of an organ pipe and the lmproved magnetic valve control.

Figure 2 is a view similar to Figure 1 showing an electropneumatic means for controlling the valve.

Figure 3 is a detail in plan showing the pivoting of the armature lever.

Figure 4 is a detail in elevation showing this pivoting.

Figure 5 is an enlarged view showing the valve and its seat.

In the embodiment of the invention shown in Figure 1 there is shown a portion of a wind chest 10 having a suitable opening 11 for the reception of the foot of a pipe 12. This opening is normally closed by a valve 13 having a leather face 14. This valve is supported by a disk 15, preferably leather, which is screwed onto a valve stem 16 rigidly selatter.

Serial No. 265,025.

cured to an armature lever 17. At 18 is an L-shaped plate or hanger secured to the top of the wind chest by screws 19, the plate carrying a thin strip of leather 20 and having an opening alined with the opening 11 and provided with turned down edges 21 against which the valve seats. The vertical leg of this hanger supports a magnet 22, a screw 23 serving to hold the magnet in position on the hanger, the screw entering the core 24 which has a beveled end 25. At the lower end the hanger 18 is slit and bent so that the edges of the slit portion are brought parallel to each other as shown at 20. The armature lever 17 has its longer arm terminating in a bent portion 26 which forms the part attract ed by the magnet upon energization of the This armature lever 17 is provided at its pivot point with spaced slits 27, the metal being bent as shown in Figure 4 to receive the pivot pin 28.

In the form shown in Figure 2 the same type of valve is employed but the stem 16 of this valve is fixed to the top of a bellows 29 which is normally held raised by the spring 30. This bellows has its bottom 31 fixed to a block 32 having a chamber 33 therein. The lever 17 has connected thereto a valve stem 3& which carries a pair of valves 35 operating in the chamber 33. This chamber is provided with a passage or port 36 communicating with the wind chest and the chamber is also provided with a second port 37 communicating with the air, the second port being normally held closed until the magnet is energized.

In the first form the energization of the magnet obviously opens the valve. In the second form the energization of the magnet opens the port 37 and closes the port 36 whereupon pressure in the wind chest will collapse the bellows and thus open the valve 13.

There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

Having thus described the invention, what is claimed as new, is:

1. An electro-magnetic valve actuating device including a support, a magnet carried by the support and having a core projecting from one end, a fulcrum member at the opposite end of the magnet, an arn'iature lever pivoted intermediate its ends to said fulcrum member and having a long arm and a short arm, the long arm of the lever extending longitudinally of the magnet and having its extremitv bent to lie adjacent said core, and a pipe controlling valve mounted on the short arm of said lever.

:2. An electro-magnetie valve actuating device including a support, a magnet carried by the support and having a core projecting from one end, a fulcrum member at the opposite end of the magnet, an arn'iature lever pivoted intermediate its ends to said tulerum member and having a long arm and a short arm the long arm of the lever extending longitudinally of the magnet and having its extremity bet to lie adjacent said core, said long arm projecting beyond the magnet and the extremit extending back toward he magnet at an acute angle to the remainder of the long arm, and a pipe controlling valve mounted on the short arm of said love.

3. An electro-magnetic valve actuating device including a support, a magnet carried bv the support and having a core projecting in one end, a fulcrum inembe' at the opposite end of the magnet, an armature lever pivoted intermediate its ends to said fulcrum member and having long arm and. a short arm, the long arm of the lever extending longitndina lly ot the magnet and having its extremity bent to lie adjacent said core, said fulcrum member and lever being each formed of plate metal, the 't'ulcrnm member being provided with spaced bent portions at its lower end and the lever being provided with a fulcrum portion positioned between the bent portions of said member, a pivot pin passing through said bent and fulcrum portions and a pipe controlling valve mornited on the short arm of said lever.

41. An elcctro-magnet-ic valve actuating th vice inclruling an -shaped hanger having horizontal and ve cal arms. the L-,--haped hanger being provided in its horizontal arm with an opening having a valve seat and constituting aport, said horizontal arm being :turther provided with screiv receiving openings for securing the hanger in position, a i'nagnet ca 'ried by the vertical arm or the hanger, an armature lever extemling Flliw stantially horizontal below said magnet and lrving a long arm attracttal by the magnet and a. short arm projecting beneath said port, and a valve carried by ll 2 short arm and controlling said port.

In testimony whereof I atii): my signature.
